SPECIFICATION forming part of Letters Patent No. 555,135, dated February25, 1896.

Application filed June 1,1895. Serial No. 551,870. (No model.)

T 0 all whom, it may concern:

Be it known that we, RICHARD IVALsH and CHARLESiYiLLmnsozucitizens ofthe United States, and residents of Newport News,county of arwick, Stateof Virginia, have invented certain new and useful Improvements inLamp-Shades, of which the following is a Specification.

This invention has for its object the utili zation of the flame, due tothe open combustion of oil, gas, or other illuminant, as a source ofenergy for producing artistic, decorative, or attractive eifects. Tothis end we suspend or support lamp-shades in such a man her and attachto them propelling-wheels having inclined vanes arranged and located soas to be acted upon by the ascending currents from the flames to whichthe shades are applied.

The shades maybe made to partly or wholly cover the flames, betransparent or translucent, or partly transparent and translucent, andbe decorated or ornamented in various colors, with various designs andscenic effects or representations of objects.

\Yith these improved shades transparent chimneys are preferably used,which, surrounding the flames, concentrate the currents produced by themand cause them to act with sufficient force to impart to the shadesrotary motion, said shades by the propelling-wheels being preferablysuspended on pointed pins held in light metal frames attached to thetops of the chimneys and acting as pivoted supports applied to thecenter of the wheels.

lYe also propose to utilize the rotation of the propelling-wheels,arranged and actuated as set forth, as an insect-dispelling device byattaching to the wheels light arms or rods extending laterally andcarrying depending ribbons or other devices which will travel around incircular paths. These devices may be used with or without the shades.

To describe our invention more particularly we will now refer to theaccompanying drawings, forming part of this specification, in which-Figure 1 illustrates our invention applied to an oil-lamp. Fig. 2 is aplan view of the same; and Fig. 3 is a side elevation of thepropelling-wheels, taken at right angles to Fig. 1. Fig. 4 shows amodification in the construction of the propelling-wheel for holding theinsect-dispelling rods.

The source of power for imparting rotary motion to the lamp-shade isrepresented as an ordinary oil-lamp, a being part of the body, I) theburner, and c the chimney. On the top of the chimney is set the tripodcl, made of wire or other suitable form of metal, so as to be light,held and clamped on the edge of the chimney by the lower parts of itslegs, which are bent to conform thereto. A vertical pointed pin (1 isfastened in the upper end of the tripod and axially arranged in relationto the chimney c.

The propelling-wheel e is made in the simplest possible manner of acircular thin sheet of metal having a central recess formed by adepression of the metal, by which recess the wheel is supported on thepin d. Curved radially-arranged slots or slits are made in the disk ofmetal and the sections formed thereby bent and inclined to constitutevanes. To provide fastening devices, by meansof which thepropelling-wheel may be centrally secured in the upper opening of theshade f, narrow strips 6 e are cut from the outer edges of the vanes e ewithout being entirely detached therefrom, said strips being bent so asto lie in radial positions and the outer ends of them bent or lappedaround the upper part of the frame or top ring f of the shade f. YVethus produce a very light inexpensive propelling-wheel particularlyadapted to the purpose for which it is designed.

The shades may be made of any shape and desigmof any suitable lightmateriahas paper, silk, 850., a preferred method of making them beingshown in the drawings, the frame or shape-retaining part of the shadeconsisting of rings f f, made of strips of cane, bamboo or any othersuitable material, the covering f being attached by pasting or otherwisethereto. Shades so made, when paper is used for the covering, will bevery light and inexpensive, and an advantage of the construction shownis that more or less of the flame may be exposed, thus regulating theamount of free light given by the lamp as desired by simply folding upthe lower edge of the shade, which will remain in any position in whichit may be placed.

The shades may be decorated by ornamental colored configurations to anyextent and in any manner taste may dictate.

To impart utility to our invention beyond that due to the shade weattachto our device an insect-dispeller, consisting of rods g g, which may befastened together by a metallic connection or be one continuous rodarranged horizontallyand carrying at the outer parts streamers orribbons g g. These rods are shown in the main figures of the drawingsattached to the vanes e of the wheel by simply bending the upper outercorners into hooks or loops 6 c on vanes diametrically arranged so as tohold the rods, as shown, when they are placed therein.

The modification at Fig. i consists in bending or folding the corners ofthe vanes 6 so as to form sockets 6'' into which the ends of theinsect-dispelling rods 9 may be placed, thus securely holding them inhorizontal position. The upper sketch shows an end view of one of thevanes so formed and the lower sketch a plan view of the same.

\Vhen our device is to be applied to a gas flame such flame will beprovided with a chimney, and it will be observed that whatever kind offlame is used the power derived therefrom, through the medium of theascending currents due thereto, will cause the shade constructed andapplied as described to be continuously and uniformly rotated as long asthe flame is burning.

The disk 71, which rests on the tripod (Z beneath the propellingwheel,is for the purpose of deflecting the currents due to the flame to causethem to act more strongly on the wheel than they would do if allowed toact directly on the central part of the wheel.

lVe claim as our invention 1. The combination of alamp-shade, and apropelling-wheel formed from a sheet of metal with radially-arrangedinclined vanes, from the outer edges of which are slit and bent narrowstrips radially arranged, and by means of which the wheel is secured tothe top of the shade.

2. The combination of a lamp-shade, and a propelling-wheel formed from asheet of metal with radially-arranged inclined vanes from the outeredges of which are slit and bent narrow strips, by means of which thewheel is secured to the top of the shade, and the upper corners of someof the vanes bent into loops or hooks, and rods provided withinsect-dispersing devices held in said loops or hooks.
